COMPENSATING SEEGIFICATION forming part of Letters Patent No. 745,568,dated December 1, 1903. Application filed July 24, 1903. Serial No.166,840. (No model.)

To all whom it may concern:

Be it known that I, CHARLES J. CALEY, a citizen of the United States,residing at New Britain, in the county of Hartford, 'State ofConnecticut, have invented certain new and useful Improvements inCompeusatingKnob- Bearings, of which the following is a full,

clear, and exact description.

My invention relates to door-knobs and to like constructions, and.particularly to compensating antifriction-bearings to be used inconnection therewith.

The object of the invention is to provide an antifriction device to beused in conjunction with door-knobs having a spindle, so that theposition and adjustment of the knob may be compensated for in anefficient and yet simple manner.

It consists in providing a yieldingantifric tion device which is locatedbetween the end of the knob-shank and the escutcheon-plate or thimblewhich is commonly employed in devices of thischaracter. This will bemore clearly seen on an inspection of the accompanying sheet ofdrawings.

Figure l is a cross-section of a knob and spindle with the compensatingdevice in position justibefore the knob is forced into place for itsfinal adjustment. Fig. 2 is a similar view showing the knobsecured tothe spindle in the customary manner, the compensating device having beenmoved into its normal operative position. Fig. 3 is an end elevation ofa portion of the compensating structure. Fig. at is a side elevation ofthe same.

,1 represents a knob which is secured to one end of the spindle 2 bymeans of a screw 3 in the customary manner.

4 is a thimble such as is commonly used with door-knobs and in this formis shown mounted on the plate 5. It is sometimes customary to form thisthimble in conjunction with the plate 5, in which instance thecombination is termed a rose-plate.

The compensating structure consists of a collar 6, which is adapted tobe inserted inside of a thimble t and which has the springs 7 7 7secured thereto on one side. These springs are preferably formedintegral with the collar, and the same may be made from sheet metal, ifdesired.

S and 9 are washers which are placed in position around the collar 6 andhave situated between their inner curved surfaces a series of balls, asindicated at 10.

In order that the structure may be compact or readily inserted orremoved when desired, the collar 6 may be spun out, as shown in thedrawings at 11, to retain the washers and 6c ball-bearings in place. Bythis construction the compensating device may be inserted or removedfrom the thimble 4, as'desired.

When the compensating structure is placed in position as indicated inFig. 1, the knob 1 may be placed on the'spindles 2 and-the end of theknob-shank pressed against vthe outer surface of the outer washer 9.When the knob is moved into position shown in Fig. 2, then the usualattaching-screw 3 may he '70 moved into place and the parts will be heldin position, it being of course understood that/there is another knob orequivalent device on the opposite end of the spindle 2, which it isunnecessary, however, to illustrate. There is, therefore, in the finalresting position an antifriction device located between the end of theknob-shank and the thimble or escutcheon-plate, so that the endthrustand side thrust are taken up in man- 8o ner to permit the knob toturn freely and yet be held securely in position.

The yielding end of the compensating structure makes it possible to useone of these devices and have it operate satisfactorily even withspindles of slightly-varying lengths, so as to prevent side play andchattering or annoying looseness in the adjustment.

What I claim is- I. In a device of the character described, a stationarysupport, a spindle, a yielding compensating device surrounding thespindle and abutting against the support and having an antifrictionbearing and a knob-shank secured in place abutting against the outer end5 of the compensating structure.

2. A device of the character described in-, cluding a support; aspindle, a knob-shank mounted on said spindle and a compensating devicelocated between one portion of the suproe port and the knob-shank,comprising a collar, springarms cooperating therewith, a pair of Washerssurrounding said collar, antifriction-balls located between saidwashers, said washers being held securely to said collar.

3. In a device of the character described, a support, a spindle, aknob-shank secured to said spindle, acoinpensating device locatedbet-ween the support and the knob-shank comprising a collar havingintegral spring-arms, an antifriction device carried by said collar,thesaid support extending overand surrounding the compensating device.

4. A device of the character described in cluding a support, a spindleextending longiitudinally therefrom, a knob-shank secured to saidspindle and a compensating device surrounding said spindle and locatedbetween CHAS. J. CALEY.
